Commercial HVAC mechanical room

Your commercial HVAC system is a huge part of what makes your building occupants comfortable and happy. The system also plays a large role in utility bills and can even have an impact on safety and health. Mechanical systems are built to last a long time but even the best systems will eventually need to be repaired or replaced. Here are some common warning signs that there is an issue in your system:

  1. New noises coming from your system. Just like with our vehicles, a strange noise is a sign that something is wrong. With your HVAC system, new noises can mean a breakdown is around the corner. If you notice new sounds, have your system looked at sooner rather than later.


  1. Strange odor. A weird smell shouldn’t be overlooked as a mere annoyance; it could be a sign that something is going wrong. For instance, a burning smell or a gas smell indicates that something in your system could be leaking. You’ll need to get your system checked immediately to eliminate the potential for a fire or explosion to occur.


  1. Inconsistent temperatures. Are occupants suddenly complaining about the temperature in the building? This may be a sign that your system isn’t working properly anymore. The fix might be as simple as a re-balance of airflow and a check of the thermostat but in some cases, your service technician may identify a more serious, underlying problem with your system.


  1. Moisture on interior of your building. Excessive moisture on the windows and walls is a sure sign that something is wrong with your commercial HVAC system. Humidity is a huge factor in keeping your facility comfortable but it can also cause mold, increased insects, and damage to equipment and even the building itself. If you notice irregular condensation or higher humidity levels than normal, call your service partner right away.


  1. Unexpected rise in your utility bills. A sudden spike in your utility bill could mean your HVAC system isn’t working as efficiently as it should be. You’ll want to have your system checked for inefficiencies. If the bills are consistently high, ask your service technician for recommendations on equipment replacements or modifications that could make your system more efficient.

Of course, it’s always best to replace your equipment before it fails. Preventative maintenance is the best way to avoid an unexpected HVAC equipment failure in your facility. With a service and maintenance schedule, issues are identified before they cause a major problem. This also provides an opportunity for improvements in efficiency to be made which save you money.
